Short Sales and Options Tax Rules (IRC Section 1233)

IRC Section 1233 contains special rules about how protective puts affect the holding period of stock. These rules prevent investors from locking in a gain with a put while waiting to qualify for long-term capital gains treatment.

Married Put and Holding Period

When an investor buys stock and a put on the same day ("married put"), special rules apply:

• The stock and put are treated as a single combined position
• The holding period for the stock is suspended while the put is open
• The holding period clock does not start running again until the put is closed, exercised, or expires
• This prevents taxpayers from locking in a gain with a protective put and then claiming long-term treatment

Example: On January 1, you buy 100 shares of ABC at $50 and buy 1 ABC 45 put at $3 (same day).

• Your stock holding period is suspended as long as the put is open
• If the put expires on June 30, your stock holding period begins running on July 1
• To get long-term capital gains treatment, the stock needs to be held for more than 12 months from July 1 (not January 1)

Exam Tip: Gotchas

• A married put suspends the holding period of the stock. The holding period does not begin until the put is closed or expires. The exam tests whether candidates understand why a protective put can prevent long-term capital gain treatment.
• Forgetting that a married put suspends the stock holding period (not just pauses it temporarily) is a common mistake.

Short Sale Rules Applied to Puts

If an investor holds appreciated stock and then buys a put (not on the same day), the tax treatment depends on how long the stock has been held:

Stock Held Short-Term (12 months or less)

• The put is treated as a constructive short sale
• The holding period of the stock may be reset or suspended
• This prevents investors from using puts to lock in short-term gains while waiting for long-term treatment

Stock Held Long-Term (more than 12 months)

• The short sale rules do NOT apply
• The investor has already qualified for long-term treatment before buying the put
• The put does not affect the stock's holding period

Exam Tip: Gotchas

• The short sale rules do NOT apply when stock has already been held long-term. Buying a put on already-long-term stock has no holding period effect.

Why This Matters

Without these rules, an investor could:

1. Buy stock on Day 1
2. Buy a protective put on Day 2 (locking in a minimum sale price)
3. Wait 12+ months
4. Sell the stock at long-term capital gains rates

The put effectively eliminates downside risk during the waiting period. Section 1233 prevents this by suspending the holding period while the put provides protection.

Think of it this way: The tax code does not let you have it both ways. If you buy downside protection (a put), you have not truly "risked" your capital, so the clock for long-term treatment stops running until that protection goes away.
